Fix reminder resend, settings validation, and notice navigation.

Reuse resolved reminder rows instead of inserting duplicates, skip failed keys in batch send, reject invalid scan settings with 400, and bind 去处理 via event delegation after async render.

+
+最后核对：2026-08-23。核对依据是当前 `main` 最新代码（`5f21527`）、数据库迁移、接口、测试和近期提交记录。
+
+这是接手本项目的第一站。阅读顺序如下：
+
+1. [项目需求](项目需求.md)：先知道系统要解决什么问题，以及哪些规则绝不能碰。
+2. [最新进度](最新进度.md)：再确认哪些能力已经真实完成，哪些仍未完成。
+3. [任务清单](任务清单.md)：最后挑选下一项工作，避免重复做已经完成的事。
+4. 需要技术细节时，再查看 `decisions/` 中的技术决定和 `issues/` 中保留的历史任务规格。
+
+## 维护规矩
+
+- 每新增、开始、完成、取消一项任务，负责的智能体都要在同一次提交里更新 `最新进度.md` 和 `任务清单.md`。
+- 新功能改变产品规则时，同时更新 `项目需求.md`；技术方案有变化时，补充 `decisions/` 的决定记录。
+- 写进手册的“已完成”必须能在代码、测试或已合并提交中找到依据；只有计划、页面演示或口头讨论的内容，一律写为“未完成”。
+- 不删除历史文档。旧内容与当前代码不一致时，在旧文件开头加“已过时，仅留档备查”提示，并在本目录写新版说明。
+
+## 旧交接说明
+
+`HANDOFF.md` 是 2026-08-06 的历史交接稿，已经不反映当前实现，保留仅作对照。当前事实以本手册三份正文为准。

+# 005 规范转账事件与双边归并技术决策
+
+对应 Issue：B-43/B-83/B-114（`docs/issues/006-p1-canonical-transfer-matching.md`）。
+
+## 分层模型
+
+- 银行源行是不可变观察；匹配层从不修改 `source_rows`。
+- 新增“不可变决定日志 + 可重建当前投影”的规范事件层：
+  - `transfer_match_decisions` 等证据表只增不改（UPDATE/DELETE 被触发器拒绝）。
+  - `current_transfer_decisions` 与 `transfer_observation_claims` 是可更新、可重建的
+    当前投影，`source_row_id` 主键保证一条观察不可能同时属于两个当前事件。
+- B-44 余额计算只读 `eligible_intercompany_events` 视图，只含
+  `active + current + classification='intercompany'`，且单边事件必须
+  `locked = 1`（管理员按证据确认）才可计算；paired 事件不受锁定状态限制；
+  单边内部、待审、同公司调拨、外部事件全部排除。
+
+## 已确认业务口径（B-114）
+
+1. 单边流水即使双方公司都能由批准账号唯一确认，也先进入未决金额，不进入 B-44
+   已确认往来余额；只有完成双边归并（`intercompany` + `paired`）或管理员按证据确认
+   （`intercompany` + locked 单边）后才可计算。
+2. 跨日事件经济日期取付款方 outgoing 银行入账时间，与导入顺序无关。
+3. 自动窗口 v1：非空参考号相同且账号镜像 <= 3 自然日（M1）；无参考号精确账号镜像
+   <= 1 自然日（M2）；别名/个人映射镜像 <= 1 自然日且参考号或摘要相等（M3）。
+   超窗或同层多候选全部进入人工审核，禁止按行号、导入顺序或名字破平局。
+4. 个人过账映射绑定具体账号、生效区间、允许方向和代表公司，必须管理员批准；
+   姓名只作辅助证据，不能单独定案。
+
+## 参与方解析
+
+- 本方：源行 `own_account` 精确命中生效期内已批准账户（`own_exact`）；缺失时才用
+  上传时持久化的批准上传账户（`upload_account`），且必须与批次公司一致。冲突进入
+  审核，不以 `company_id` 或户名反推。
+- 对方：严格按账号层解析——精确账号 -> 已审核账号别名 -> 已批准且在窗口内、方向
+  允许的个人过账映射；每层唯一最佳结果才继续。户名/户名别名只用于一致性/冲突证据，
+  冲突降级到审核。
+- 方向：`expense > 0 且 income = 0` 为 outgoing；`income > 0 且 expense = 0` 为
+  incoming；双正/双零/负数/缺币种进入 `unresolved`。金额用 `Decimal` 精确相等，
+  不设手续费容差。
+
+## 匹配与状态机
+
+- 候选硬门槛：双方工作表 confirmed、方向相反、金额与币种相等、公司端点互为反向。
+- M1/M2/M3 唯一候选自动 paired；R1（端点可确认但镜像/参考号证据不足）与 R2（同层
+  多候选）进入 `needs_review`；待审行不能被其他自动匹配抢占。
+- 状态：`unresolved -> internal_single -> matched`、`needs_review -> matched |
+  same_company_transfer | external`；单边确认两端同公司立即为同公司调拨。
+- 幂等：rule_version + 当前观察集合 + 证据未变时零写入；locked 人工决定自动重跑
+  跳过；纠错只能通过 `reverse`（`mode='reversal'` 新记录）+ 原因，之后允许重跑。
+
+## 事务、并发与回滚
+
+- “确认工作表 + 为新增确认行建立/更新事件 + audit”在同一个服务事务，任一失败整体
+  回滚，不存在 confirmed 但未匹配的半成品。
+- 独立重跑使用 `BEGIN IMMEDIATE`，按 `source_row_id` 升序写，SQLite 30 秒 busy
+  timeout 保留；投影可从只增日志重建（`rebuild_current_projection`）。
+- migration down 只用于测试/上线前回退；生产产生决定后默认保留 migration 5 与审计
+  数据，不执行破坏性 down。
+
+## Decimal
+
+金额全程以规范十进制字符串存储和比较，任何路径都不转 `float`；`100.0` 与 `100.00`
+视为相等，`100.00` 与 `100.01` 不匹配。

+# 最新进度

+
+## 已经真实完成
+
+- 支持中信、农行、工行、建行、河南农商行、郑州银行六类样本的 `.xls` / `.xlsx` 流水解析；能识别变动的表头位置和列顺序，并校验余额连续性。
+- 已有 SQLite 数据库和 5 次版本迁移。原始文件按内容哈希保存，导入批次、工作表、源行和异常都有记录；原始文件、工作表和源行被数据库规则保护，不能直接改或删。
+- 已实现管理员与公司用户登录、首次改密、会话失效、登录失败限流、服务端权限隔离和审计记录。
+- 已实现公司、用户、银行账户、别名等主数据管理；公司提交的银行账户需管理员审核后才能参与上传和识别。
+- 已实现导入、逐工作表确认或忽略、失败诊断、重复上传处理和 CSV 导出；未确认的工作表不进入后续处理。
+- 已实现规范转账事件和双边流水匹配。匹配决定保留历史，无法自动判断的记录进入人工审核；同公司调拨、外部流水和未锁定的单边记录不进入已确认的公司间往来。
+- 已有登录页、总账端和公司端页面，最近一次合并完成了登录页视觉改版。
+
+## 仍未完成或不能当成已完成
+
+- 公司间余额与会计科目的正式计算、已批准手工记录入账和逐层余额追溯尚未完成。
+- 全局起算日、期初余额、流水覆盖断档、无业务校准、月结、重开和调整审批尚未完成。
+- 提醒、完整的服务端查询导出，以及前端彻底移除演示数据和浏览器本地业务状态尚未完成。
+- 生产部署所需的 HTTPS、反向代理、备份、监控和正式运行保障尚未完成；本项目当前只允许测试环境部署。
+
+## 最近验证
+
+2026-08-23 已运行完整 Python 自动化测试：解析、持久化、认证与权限、导入接口、主数据和双边匹配相关测试均通过。后续修改功能时，必须再次运行完整测试并在本文件记录结果。

+# 项目需求
+
+## 这个系统做什么
+
+这是河南金牛实业集团有限公司内部各公司之间的资金往来管理系统。它把各公司的银行流水集中起来，识别同一笔公司间转账的两边记录，形成可以一路查回原始银行流水的往来结果。
+
+系统有两个独立入口：
+
+- 总账管理端：管理公司、公司账号、银行账户、导入记录、异常和公司间转账匹配。
+- 公司出纳端：只处理本公司的账户登记、流水上传、工作表确认和本公司相关异常。
+
+## 必须做到的业务规则
+
+- 银行原始文件和原始流水是证据，导入后不能直接修改或删除；修正必须通过可追溯的审核决定、冲销或调整完成。
+- 一笔公司间转账的收、付两边只能算作一个经济事件，不能因为有两条银行流水就重复计算。
+- 同一家公司不同银行账户之间调拨，不计入公司间往来。
+- 账号、金额、方向、日期和余额等可核对信息优先于户名；信息不完整或有歧义时进入异常审核，不能猜。
+- 已确认金额和待确认金额必须分开；所有余额都要说明统计截止日期和未决金额。
+- 公司用户只能查看、上传和导出本公司的数据。这个限制由服务端执行，页面上“看不见”不等于有权限限制。
+- 起算日前的流水必须保留，但不参与期内计算；期初余额、流水覆盖断档、无业务校准、月结和调整都要留痕。
+
+## 当前技术边界
+
+项目使用 Python 标准库服务、SQLite 数据库和浏览器页面。银行模板支持 `.xls` 与 `.xlsx`，按表头识别而非依赖固定行列。金额使用精确十进制，真实运行数据放在 `data/`，不进入代码仓库。
+
+系统目前仍是测试环境项目，不能当作已完成生产部署：正式上线前仍需补齐核算、期初与断档、月结、备份、监控和 HTTPS 等能力。

-      OWN-WORLD: 深黑身份场景、石墨玻璃表单和荧光绿当前状态，延续双端工作台的材料语言。
-      STORY: 居中集团登录卡：先确认集团身份与系统名称，再选择工作端口登录。
-      FIRST VIEWPORT: 一张悬浮玻璃登录卡居于氛围光中央，集团名称置顶，端口选择、账号表单与系统事实依次排列。
-      FORM: 用户参考图锁定的深色玻璃财务工作台，Operate 模式；seed key fe8a50aa。
-      FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, and DESIGN.md
